Development of a carbon quantum dot-based sensor for the detection of acetylcholinesterase and the organophosphate pesticide.

In this study, a proper and reliable fluorometric method is introduced for screening acetylcholinesterase (AChE) and its inhibitors, using carbon quantum dots (CQDs) as the signal reporter. Pure, S-doped, and P-doped CQDs, were synthesized and their recoverable fluorescence quenching properties were observed, when exposed to Hg, Cu, and Fe quenching ions, respectively. The study on the recovery of their emission showed that after the introduction of another guest substance with a stronger affinity to the quenching ions, their fluorescence is restored.

The benefit of intravenous immune globulin in the treatment of delayed radiation myelopathy.
